PowerPoint Viewer lets you view full-featured presentations created in PowerPoint 2010 and previous versions. This viewer also supports opening password-protected Microsoft PowerPoint presentations. You can view and print presentations, but you cannot edit them in the PowerPoint Viewer.

The following Microsoft PowerPoint features are not supported by this viewer:

Information Rights Management (IRM) presentations.

Running macros, programs, or opening linked or embedded objects.

Note: PowerPoint Viewer registers itself with the .ppt, .pot, and .pps file extensions only if a version of PowerPoint is not installed on your computer. If registered, double-clicking on these file types will launch PowerPoint Viewer.
